Chrysanthemum plant named ‘PPP TER Y05’

ABSTRACT

A new and distinct  Chrysanthemum  plant cultivar is disclosed, characterized by large decorative type inflorescences, consistent flowering response to short days, blooming consistently after 49 days of short day length, bright yellow ray florets, free branching habit, and a consistent natural season flowering habit during the last two weeks of August.

Latin name of the genus and species: Chrysanthemum morifolium.

Variety denomination: ‘PPP TER Y05’.

BACKGROUND OF THE INVENTION

The new cultivar ‘PPP TER Y05’ is a product of an induced mutation of the parent Chrysanthemum plant variety ‘GEDI ONE TER’ (U.S. Plant Pat. No. 13,885) using gamma ray treatment at a dose of 20 Gy. The new cultivar was discovered and selected by Dirk Pieters in October 2003 in Oostnieuwkerke, Belgium.

Asexual reproduction of the new cultivar ‘PPP TER Y05’ by terminal cuttings and tissue culture was performed in Oostnieuwkerke, Belgium, and has shown that the unique features of this new cultivar are stable and reproduced true to type on successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘PPP TER Y05’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘PPP TER Y05’. These characteristics in combination distinguish ‘PPP TER Y05’ as a new and distinct Chrysanthemum cultivar:

-   -   1. Large decorative type inflorescence;     -   2. Consistent flowering response to short days, blooming         consistently after 49 days of short day length;     -   3. Free branching habit; and     -   4. Consistent natural season flowering habit during the last two         weeks of August.

Plants of the new cultivar ‘PPP TER Y05’ are similar to plants of the parent variety, ‘GEDI ONE TER’, in most horticultural characteristics, however plants of the new cultivar ‘PPP TER Y05’ has more ray florets than the ray florets of the parent variety. Additionally, the new variety is shorter than the parent and also has different color ray florets than the parent.

In comparison to the commercially available variety ‘GEDI ONE YLCEL’ (U.S. Plant Pat. No. 13,903). ‘PPP TER Y05’ has brighter yellow ray florets. Additionally, the new variety ‘PPP TER Y05’ naturally blooms approximately three weeks earlier than the comparable variety. Further, the new variety ‘PPP TER Y05’ has a larger diameter inflorescence and has more inflorescence per flowering branch than the comparable variety ‘GEDI ONE YLCEL’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘PPP TER Y05’ grown in a 2 gallon container. One cutting was used in the pot, planted mid May and grown under outdoor field conditions. The colors are as nearly true as is reasonably possible in a color representation of this type.

OTHER CHARACTERISTICS

-   Disease resistance: Neither resistance nor susceptibility to     diseases or pests has been observed in this variety. -   Drought tolerance/cold tolerance: Flowering plants are hardy to low     temperatures about −2° C. Non-flowering plants are hardy in the     approximate range of 3° C. to −6° C., depending upon duration of     cold and amount of moisture in the soil. With adequate water plants     are hardy to a high temperature of 45° C. -   Fruit/seed production: Commercially, this plant is not used or     observed in a stage where seeds would be produced. Therefore, seed     production has not been observed.
